Analisis Dampak Air Asam Tambang Batubara Terhadap Kualitas Air Sungai dan Dampaknya Bagi Masyarakat Pengguna Air Sungai
No full textThis study aims to examine the impact of AAT on the water quality of the Purian River and its implications for communities that depend on this water source. Acid mine drainage, which is formed due to the oxidation of sulfide minerals, can reduce water quality, potentially affecting the health and economy of the user community. The research methods applied include quantitative and qualitative approaches. The analysis was carried out using a correlation test to measure the relationship between water quality between the point of compliance and the Parambahan River, and the Chi-Square test was used to evaluate the relationship between seasonal mining activities and health problems experienced by respondents. In addition, a survey was conducted to explore local community perceptions regarding the impact of river water. The results of the study indicated mild pollution in several water quality parameters, especially TSS and heavy metals, which exceeded the quality standard limits. Water quality status was measured using the Pollution Index based on PP No. 22 of 2021 and Kepmen LH No. 113 of 2003. The results showed that most samples were classified as mild pollution. Correlation analysis indicated that AAT was not the only factor causing pollution, due to seasonal mining activities and the contribution of water use for livestock farming practices. The conclusion is that waste management carried out by PT. AICJ meets government quality standards, at 66.67%, but respondents still feel negatively affected by mining activities.Penelitian ini menganalisis dampak Air Asam Tambang (AMD) terhadap kualitas air sungai dan implikasinya terhadap kesehatan masyarakat sekitar di Sungai Purian, Sijunjung. Kualitas air diukur dengan metode Indeks Pencemaran (IP) dan dievaluasi berdasarkan baku mutu Peraturan Menteri Lingkungan Hidup Nomor 113 Tahun 2003 untuk limbah pertambangan batubara, Peraturan Menteri Lingkungan Hidup Nomor 5 Tahun 2022 untuk air sungai golongan 2, dan Peraturan Menteri Kesehatan Nomor 32 Tahun 2017 tentang bidang kesehatan. Hasil penelitian menunjukkan meskipun kualitas air masih memenuhi baku mutu limbah pertambangan, namun terdapat dua titik sampel yang masuk kategori “cemar ringan” jika diuji dengan standar air kelas 2 dan kesehatan masyarakat. Pengelolaan DAL yang dilakukan oleh perusahaan pertambangan dengan kolam sedimentasi dan penambahan kapur telah membantu menurunkan kandungan logam berat seperti Fe dan Mn, serta menstabilkan pH air. Namun terdapat hubungan yang signifikan antara paparan air tercemar AMD dengan gangguan kesehatan, terutama pada penambang musiman yang sering bersentuhan langsung dengan air sungai, dengan keluhan umum berupa gatal-gatal. Persepsi masyarakat sekitar juga menunjukkan kekhawatiran terhadap perubahan kualitas air sungai yang terlihat dari warna air yang semakin keruh. Temuan ini menekankan pentingnya pengelolaan DAL yang lebih baik dan keterlibatan masyarakat dalam pemantauan kualitas air untuk mengurangi dampak negatif terhadap kesehatan dan menjaga keberlanjutan ekosistem perairan di sekitar area pertambangan

Immune Activity of Vannamei Shrimp (Litopenaeus vannamei) Under Ozonated and Non-Ozonated Treatments
No full textThis study aims to analyze the effect of ozonation treatment on the immune activity of vannamei shrimp, compared to non-ozonization treatment. Parameters measured include Total Haemocyte Count (THC), Differential Haemocyte Count (DHC), and phagocytic activity. The results show that ozonation treatment produces higher THC values, namely an average of 75% more than non-ozonation. The DHC value in the ozonation treatment showed an increase in granular cells by 40% compared to the non- ozonation treatment. In contrast, hyaline cells decreased due to a more active immune response against pathogens. Phagocytic activity in the ozonation treatment reached 15%, higher than non-ozonization which only reached 10.33%. These data indicate that ozonation plays an important role in improving shrimp's immune response by reducing the water's pathogen content and minimizing stress. In conclusion, ozonation was proven effective in increasing the immunity of vannamei shrimp by supporting key immunological parameters

Phytochemical Analysis, Physical Properties, and Chemical Compound Content White Teak Wood (Gmelina Arborea Roxb)
No full textIndonesia is a country with a tropical climate. Rainfall in Indonesia is quite high and greatly affects the growth of mushrooms (fungi). The use of wood cannot be separated from the manufacture of traditional houses. These traditional houses made of wood are very susceptible to fungal attacks. Wood or wood rot fungi are fungi that live attached to decaying trees, but some types of wood fungi grow on living tree trunks and on dead trees. Wood rot fungi are heterotrophic, or do not produce their own food, This study aims to determine the resistance of white teak wood (Gmelina arborea Roxb) against wood-decay fungi. The research method used was a completely randomized factorial design consisting of two factors: factor I (wood) and factor II (fungi). The test samples used for the combination of the two factors measured 5x 2.50x1.50 cm, with a total of 9 test samples placed in culture jars separately. All samples from the base, middle, and tip tests were placed into a jar containing PSA media, and the inoculated mushroom culture was added to the jar. The observed parameters used an analysis of variance to determine whether the treatment had a significant effect on the decrease in teak wood weight. The Least Significant Difference (LSD) test was carried out to determine whether there were significant differences between treatments or not
